About the Airtac SAID40 Double Rod Cylinder SAID40X950S
The AirTAC SAID40X950-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 950mm stroke and a built-in magnet for position sensing. Because the twin rods occupy both sides of the piston, the annulus area is identical in each direction, yielding equal push and pull forces. This 40mm bore generates 528N both ways at 0.5MPa and 739N at 0.7MPa.
A rod exits both end covers, allowing you to mount the primary workpiece on one side and a position flag or secondary cam on the rear. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic switches. Carbon steel rods and standard TPU seals suit general industrial temperatures from -20 to +70 C.

Where the Airtac SAID40 Double Rod Cylinder SAID40X950S Is Used
Symmetric Force Transfer
Drives a shuttle mechanism where the equal 528N push and pull forces at 0.5MPa ensure consistent momentum and cycle times in both directions.
Rear-Rod Position Sensing
Mounts the primary tool on the front rod while the rear rod carries a DMSE electronic sensor flag, keeping switches safely away from the main work area.
Anti-Rotation Slides
Utilizes the twin-rod architecture to guide a lifting slide, preventing torsional twist without requiring external linear bearings.
Is the Airtac SAID40 Double Rod Cylinder SAID40X950S the Right Cylinder?
Select this 40mm bore when an application requires balanced 739N force at 0.7MPa in both directions; step down to a 32mm bore for lighter 483N loads, or up to a 63mm bore for 1962N. The double-rod design is chosen over a single-rod SAI when dual-side guidance, anti-rotation, or rear-rod sensing is required. This 950mm unit is a non-standard stroke exceeding the 800mm standard maximum, making it a made-to-order item.
At 950mm, the unsupported stroke length is substantial; always use an external guide to prevent rod-bearing bending and side-load damage. The PT tapered port is G1/4. Mounting accessories use the SAID set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR. Note that air cushions only decelerate the piston near stroke end; this cylinder will drift if air pressure is lost, so use a SAIL lock or BSAID clamp-lock for position holding.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAID40 Double Rod Cylinder SAID40X950S FAQ
Because the double-rod design has equal annulus areas on both sides, it provides 528N of force in both extend and retract directions at 0.5MPa, and 739N at 0.7MPa.
Yes, it is dimensionally interchangeable per ISO 15552 mounting dimensions. It uses a profile barrel and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, making it a drop-in replacement for other ISO 15552 double-rod cylinders.
